Preface
Welcome to the seventh edition of The Gypsum Construction
Handbook. This edition is the successor to a long line of earlier ver-
sions stretching back for more than a hundred years. Since it was
first published in 1905, the Handbook has been a trusted reference
and an invaluable toolbox companion. We believe this latest edition
will faithfully maintain and build on that century-long tradition of
excellence.
The people of USG are honored to provide the Handbook in light of
the book’s heritage and relevance to the building industry. This seventh
edition, like its predecessors, represents a true collaborative effort on
the part of our company, our people and our partners. It pools the
collective experience, best knowledge and practices, and hands-on
expertise of hundreds of USG employees. And it draws from USG’s
long history of innovative research and product development, cutting-
edge production technologies, and the delivery of high-performance
solutions—decade after decade.
The Handbook symbolizes USG’s total commitment to our customers
and our industry. Our dedication to unwavering service, state-of-art
products, dynamic leadership and the development of lasting rela-
tionships motivates us to go the distance in everything we do—with
no short-cuts and no tolerance for less than our best effort. We want
the professionals who use our products to be confident that USG will
deliver innovative, high-performance building solutions every time.
USG partners with our customers and inspires them to create the
outstanding spaces where people live, work and play. We are proud
of our products and the dedication and creativity inherent in produc-
ing them. We will continue to focus our company and people on the
development of new materials, broader applications, and improved
construction technologies—such as our game-changing portfolio of
lightweight building products.
The Handbook is just one of the many ways we strive to exceed your
expectations and we hope it serves as an indispensable resource for
each of your construction projects.
It’s Your World. Build It. We can help.
Sincerely,

Jim Metcalf
Chairman, President and CEO
USG Corporation
